1. Richer Table Scraps
According to the study:
The more than 40 percent jump in body weight in feral rats scavenging on the streets of Baltimore may reflect the increasing richness of their diet as they feed on our more calorie-dense refuse.
Animals that feed on our table scraps are getting as fat from it as we are. Fifty years ago our table scraps were less likely to be an extra value meal from your local fast food chain and this is true of household pets as well. If you’re feeding them human food and you don’t eat healthy, they won’t be eating healthy either.
2. An Indoor Lifestyle
Nearly 89 million American pets are overweight or obese according to the Association for Pet Obesity Prevention. And just like in humans, such weight problems put them at risk of diabetes, arthritis, high blood pressure, and a multitude of other diseases.
Like person like pet, our household pets follow our directions. If you’re active and love playing outside, you’re more likely to take your pet on walks, throw the ball outside, and take them on hikes. On the other hand, our increasingly indoor society means that animals are spending more and more time asleep on the couch while we watch television. Your cat may watch a bird on the tube, rather than venturing outside to catch it. According to Cairn Rescue, outdoor cats and house cats that roam outside typically do not get fat. It’s cats that are left indoors that suffer from boredom and lack of exercise.
